Parentage uncertain...References describing Persian Yellow as a parent ignore the fact that Persian Yellow (introduced only in 1838) was not in commerce at the time that Harisonii was introduced in the 1820's. Writers contemporary to Harison referred to one of the parents as the yellow briar, which is not the same as Persian Yellow. For many years Persian Yellow was reported as a parent of Harison's Yellow.

The Swedish Rose Society recommends Harisonii for northern Sweden.

Although Harison's Yellow has been considered tetraploid for many years, many plants labeled as Harison's Yellow are triploid. At least 2 genotypes are in commerce as Harison's Yellow.
